Command Explanations
To view instantaneous metering values, enter the following command:
=>MET k <Enter>
where k is an optional parameter to specify the number of times (1–32767) to
repeat the meter display. If k is not specified, the meter report is displayed
once.
MET M (Maximum/Minimum Metering)
The MET M command displays the maximum and minimum values of the
quantities in Table 10.13.
To view maximum/minimum metering values, enter the following command:
=>MET M <Enter>
Use the MET M R command from Access Level E or higher to reset the
maximum/minimum values. All values will display
RESET until the SEL-734
records new maximum/minimum values.
For more information on maximum/minimum metering, see
Maximum/Minimum Metering on page 4.16.
MET PM (Synchrophasors)
The MET PM serial port ASCII command displays synchrophasor
measurements, as Table 10.14 describes. The MET PM command operates
only when EPMU = Y and the Meter Word bit TSOK := 1. The TSOK Meter
Word bit indicates that the IRIG-B signal is sufficiently precise to time-stamp
synchrophasor data.
The synchrophasor data are also available via the Tools > Meter & Control >
Meter & Control (HMI) menu in
ACSELERATOR QuickSet software, and has
a similar format to Figure 10.9.
